Patented Jan. 14, 1941 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to hand operated looms and more particularly totoy looms for use as a pastime to weave plain, and. decorative, fabricsfrom various colored yarns, twines, and kindred supplies.

The principal object of my invention is to provide a loom of aboveclass, inexpensive to build, of sturdy nature and appealing to andcapable of being operated by comparatively young children to weaveuseful familiar objects, and be of interest to grown people.

A further object of my invention is to provide a loom of this type withmeans to relieve the friction at contact part of warp threads and heddleeyes, to avoid undue breakage of the warp threads, also to automaticallyassemble the heddle eyes to a position for easy rethreading.

The above objects are attained by the construction and operation asherein explained and shown.

In the drawing:

Fig. 1 is a cross section side view lengthway of the loom.

Fig. 2 is a cross section front view widthway of the loom, looking fromleft to right.

Fig. 3 is a front view of the heddles and their operating mechanismdetached from the loom.

Fig. 4 is a detail view of heddle movement control.

The loom framing, in the shape of an openbox, comprises a base part, I,side pieces, 2, 3, and end pieces, 4, 5, suitably secured together. Thisform of frame construction serves the double purpose of supplying aframe for the loom and a box in which can be contained odds and ends achild would acquire during operation of the loom. I

Secured to side pieces 2, 3 are vertical side pieces, 6, I, supportingrollers 8, 9. Roller 8 is provided with a groove, I0, pin, II, and pinI2 hereafter referred to. Engaging rollers B, 9 in an oblique manner,hereinafter referred to, are heddles, having metal warp eyes, I3,coupled in pairs by twine loops, I4, the knots, I5, of the loopsengaging roller 8 engaging in groove I0 of said roller 8.

Fast in side piece I is a pin, It, engaging a spring, H, in contact withpin I2. Provided at the top end of side piece I are shoulders, I8, andthe end, I9, of piece I, is curved to allow movement of pin I2 from oneshoulder to the other during the turning of roller 8. Loosely secured onpiece I by screw, 20, is a slotted plate, 2I, which, when it is desired,or necessary, to rethread the heddles with warp threads the roller 8 isturned to position the pin I2 and slotted plate 2| pushed upwards inengagement with said pin I2.

Lengths of Warp threads, 22, 23, are threaded through mail eyes I3 andtheir ends secured to hooks 24 fast in the top edges of end pieces 5, 6,and roller 8 is then turned backwards and forwards thus formingalternating Warp sheds in which picks of weft are inserted and. pushedforward, in the absence of a usual reed, by the edge of the fiat shuttleused or by the aid of a comb.

The pin II offers a convenient meansto turn roller 8 and pin I 2 andspring I! serve to hold roller 8 in its turned position and keep thewarp shed open while picks of weft are inserted. The above explainedprocedure weaves what is known as plain clot or a tabby weave. To formdesigns, stripes of various colored-warp threads with stripes of coloredweft picks can be used to Weave differing designs. Another form ofdecorative cloth can be made by, after the regular weft pick has beeninserted, and while the warp shed is open, inserting short lengths ofweft picks of a different color or kind. It will be seen that the maileyes I3 are positioned, Figs. 1, 2, to the rear of the heddle rollers 8,9, to form one warp shed and change to the front of the rollers uponforming the opposite warp shed. This action gives the mail eye I3 asliding motion, forwards and backwards, on its respective warp threadthus distributing the frictional contact over a length of the warpthread and reducing the thread breakage.

As shown in Fig. 3 the roller 8 is set at half turn and mails, I3,brought together to simplify the rethreading of the warp threads intheir mails.

The thickness of the Warp threads, their size and the number of heddlesemployed would determine the kind and quality of cloth woven. Thisknowledge would be acquired by the experience of the child operating theloom.

While I have described in detail one embodiment of the invention it isunderstood that changes can be made in the shape, size, and constructivedetails without departing from the spirit of my invention or the scopeof the following claims.

I claim:

1. A toy loom having a frame provideed with two uprights, two rollers,one above the other, rotatably mounted in said uprights, heddles oiflexible material passing around both rollers and secured to the upperroller, each heddle having a figure eight formation, turning movement ofthe upper roller in one direction or the other causing a shifting of theheddles to produce sheds, a pin extending from one end of said upperroller eccentrically thereof, the corresponding upright having two stopshoulders cooperating with said pin to limit the turning movement of theupper roller in either direction, and a spring connected to said pin andadapted to hold the latter yieldingly against either shoulder.

2. A toy loom comprising a frame, two rollers rotatably mounted therein,heddles of flexible material passing around both rollers and secured toone of them, each heddle having a metal eye for the warp thread, turningmovement in one direction or the other of the roller to which theheddles are secured causing a shifting of the heddles to produce warpsheds, a pin extending from the end of said roller eccentricallythereof, stop shoulders cooperating with said pin to limit the turningmovement of the roller in either direction, a spring connected to saidpin and adapted to hold the latter yieldingly against either shoulder,and a slotted plate slidably carried by the frame and adapted to engagesaid pin when the roller is in mid-position, thereby holding the heddleswith all the metal eyes in alinement.

JOHN C. BROOKS.
